"Be it hown that I, GOTTFRIED Manes, a

citi zen of the German Empire, residing at Duisburg, in the Kingdom of Prussia, Gen many, have invented certain new and useful This invention has for its object to make such lubricating-pad frames applicable also to longitudinally-movable axles, and thus to prevent the cutting of the lubricating-pad carrier, usually made of iron plate, into the rounded-off portion of the axle-journal.

Several constructions of the device according tov this invention are illustrated by way of example in the accompanying drawings, in which F i ure 1 is a longitudinal section through the ame; Fig. 2, a cross-section thereof; Fig. 3, a side elevation of another construction of the frame ,Fig. 4, a front elevation of vation of'a third construction'of the frame; Figs. 6 and 7, a front elevation and longitudina section of the frame shown in Fig. 5.

The frame shown in Figs. 1 and 2 is constituted by the top plate 1, forming the sup port or carrier for the lubricating-pad 2, and a bottom plate 3, a helical s ring 6 being arranged between the two an ressing the lubricating-pad frame from be ow against the axlejournal shown dotted in Fig. 1.

The to plate 1 is secured to a cross bar or part 5, t e ends of which are rovidedwith sldt-shaped openings, throug 1 which pass vertical side guides 4. Owing to the latter being bent at their upper ends at 7, a slipping off or disengagement of the bar 5, and therefore of the top plate 1, from the guides 1s precluded. I

In order to enable the to plate to move longitudinally relatively to the bottom plate,

the vertical guides 4 are not connected directl to the bottom plate 3, but aremade longitudinally adjustable relatively to the latter. mounted on the bottom plate, and the guides are secured to said plate. The edges l d of .ary the frame shown in Fig. 3; Fig. 5, a side ele- To that end a second plate 9 is' bent upward, while t e edges 11 of the plate 9 are folded round the said longitudinal edges. They form thus to ether an angular rectilinear guide, which ma cos a longitudinal movement ossible without the plate 9 moving on the ottom of the axle-box. p

The edges 12 of the bottom plate 3 extending transversely of the axle are cent u at a right angle in order to prevent the p ate from slidin ofi from the plate 3.

The cons ruction illustrated in Figs. 3 and 4 differs from that shown in Figs. 1 and 2, as

the longitudinal guide is arranged at a different point between the frame parts. In this construction the pad-carrier 1 is not secured to the transverse bar 5: The pad-carrier 1 is provided with four eyes or sockets 13 and the cross-bar with two eyes or sockets 14, arranged in such manner that a rod or a wire 1.5 on either side can be passed through two sockets 13 and one socket 14. This wire can be secured either to the sockets 13 or to the sockets 14. The action is the same in both cases, viz: the pad-carrier can be shifted longitudinally relatively to the cross-bar, only in one casethe wires move with the pad-carrier and in the other case they remain station- In the construction illustrated in Figs. 5, 6, and 7- the cross-bar 5 is slidable vertically upon the vertical side guides 4 in the same way as in the preceding construction. Two brackets 20 are connected to the cross-bar 5, the )adcarfier sliding on their lateralparts parallel to the axle by means of eyes or sockets 19. The pad-carrier in this case is not in one piece, however, but is divided in the center transversely of the axle, and thus fo'rms two parts '17 18, which can make longitudinal movement independently of each other. For bridging over the intermediate space between the two plates l7 18 the lubricatingad 2 rests on a support .16, of felt, so that the lhbricating-pad is suliic'ently pressed against the axle-journal even in the intermediate space. This arrangement makes it possible for one of the two )BJtS of the padcarrier to give way" independ event of an longitudinal shocks, so that there is abso utely no risk of damage to the axle-'ournal.

I clai m 1. The combination, with a lower late 9,

,and vertical side guides 4 connected t ereto; of a cross-bar 5 slidable vertically on the sa d ently of the other in the the bottom plate 3 arallelto the axle are side guides, a spring interposed between the said lower plate and cross-bar, a pad-plate supported by the said crossbar, and guide mechanism permitting the said pad-plate to slide longitudinally.

2. The combination, with a lower plate, and guides connected with it; of a cross-bar slida'ble vertically on the said guides, a spring interposed between the said plate and eross-bar, and means for supporting the luhricating-pad carried by the said cross-bar and free to slide in a horizontal plane.

3. The combination, with a stationary bottom plate having upwardly-projecting edges,

seems a lower plate; 9 provided with guides which are slidahle longitudinally on the said edges, and vertical side guides 4 connected to the said plate 9; of a cross-bar 5 slidable vertically on the said side guides, a spring interposed between the said lower plate and cross-bar, and apad-plate supported by the said cross-bar.

In testimony whereof I affix my signature in presence of two witnesses.
